VERTICAL LOOSE-LEAF-BINDING MACHINE.

Specification of Letters Patent. Paige'ntgd Aug 8, 1922 Application filed June 9, 1921. Serial No. 476,272. I

T 0 aZZ whom it may concern Be it known. that I, HENRY M. CRIPPEN, a citizen of the United States, residing at Athens, in the county of Athens and 'State of Ohio, have invented certain new and useful Improvements in Vertical Loose- Leaf-Binding Machines, of which the following is a specification.

My invention relates to improvements in the lose leaf binding machines shown in my Patents 1,255,112, January 29, 1918, and 1,346,179, July 13, 1920.

The objects of the invention are to provide a vertically operating punching mechanism in a plane parallel to the receiving pins in order to lessen the length of throw of the punching head in its movement of transferring the punched sheets to the receiving pins; to actuate the punching mechanism indirectly through gearing in stead of directly by a lever whereby the length of throw of the punching head is lessened or shortened as before referred to; to provide an improved base and locking means for the receiving pins; to provide.

improved clamp and sheet-carrier operating mechanism; to provide improved stripper mechanism for the punches; to provide an improved form of locking means for the clamp bar against which the pile of sheets is compressed; to simplify and strengthen the main frame or casting carrying the anvil housing, fixed axle and mechanism mounted thereon; provide improved sheetguiding or gaging devices and to generally simplify and improve the constructions of the patents referred to, while still retaining the basic features thereof.

These objects I accomplish by the con struction shown in the accompanying drawings. in which:

Fig. 1 is a side elevation partly in section of my improved machine. r

Fig. 2 is a plan view thereof with the sheet carrier partly broken away. 7

Fig. 3 is a vertical longitudinal section thereof with the parts ready to begin the punching of the sheets; the gages being omitted.

Fig. 4 is an elevation partly in section looking at the right hand end of the machine.

Fig. 5 is a vertical longitudinal section with the sheet carrier compressing a pile of sheets.

Fig. 6 is a sectional elevation of the right hand end of the machine, showing the carrier swung up with a punched and compressed pile of sheets.

Fig. 7 is a detail perspective partly in section of the main square axle with the tiling pinsthereon.

Fig. 8 is a detail elevation to better show the compact relation of the actuatinggear, operating hooks or cams, the ratchet and adjacent parts.

Fig. 9 is a perspective of the sheet clamp.

Fig. 10 is a section on line 10-1O of Fig. 11.

Fig. 11 is a bottom plan view of the inner end of the sheet carrier and adjacent parts.

Fig. 12 is a fragmentary vertical section, showing the sheet carrier moved to the right by lever 95.

An open rectangular base 1 is provided which may be cast or formed of sheet metal, as may be desired. The longitudinal sides of the base 1 are provided adjacent to one end with uprights 2, 2 connected at their upper inner sides to the top crossbar 3 of a vertically disposed main frame or casting 4, the side arms of which extend downward to the lower edges of the sides of the base 1, where they are apertured for the passage of the main operating rock shaft 10, the ends of which are mounted in bearings 11 on the outer sides of the base; one end of the shaft extending beyond the side of the base where it is provided with any desirable operating means, a vertically disposed lever 12 being shown for this purpose. This rock shaft 10 is provided within the base 1 with two mutilated gears 18, 13, one at each end. Upon the inner side of the crossbar 3 is formed the tubular anvil casing 14 for the tubular adjustable anvil 15 provided as in my said patents with series of punch apertures 16 with the middle set of which a transverse slot 17 in the anvil casing 1 1 registers. By passing a pin (not shown) through this slot 17 into one of the apertures 16 the anvil 15'may be turned to'bring any series of apertures in line with the punches to be presently described. The ap ertures 16, when so adjusted for operation, face upwardly and the upper surface of the anvil casing forms a horizontal transverse ledge or support for the ends of the sheets to be punched. The anvil 15 is open at its ends and these open ends are in line with apertures 5, 5 inthe uprights 2, 2, so as to permit the insertion and removal of the drawer 6; this drawer being like the one shown in Fig. 13 of my Patent 1,346,179 so that no further description of it is necessary. The inner vertical face of the crossbar 3 is provided with a gage plate 19 having operating pins 20 extending through apertures in the crossbar and provided with upturned ends 21 engaged by inclined slots 23 formed in an operating slide 22, held in its'adjusted. position by an angle clamp 24, mounted on a clamping screw 25 threaded into the outer face of crossbar 3. By adjusting the gage plate 19 towards and from the anvil apertures 16 the ends of the sheets will engage the same and the point where they will be punched will be set or determined.

Near the lower ends of the side bars of frame 4 and on the inner edges thereof are formed projections 7, 7, which are transversely apertured for the passage of two journal pins 30, the inner ends of which ex- 7 tend into a transverse fixed axle 31 which lies parallel to the anvil 15. These journal pins 30 are secured to the axle 31 by two vertical pins 32 which project above the axle so as to enter apertures 34 in the base 35 of the filing pins 36. The lower side of this base 35 is fiat to engage the flat upper side of the axle 31. This lower side of the base 35 is provided with a cushion 37 of some softmaterial, such as felt, so as not to mar the desk tops or the like. The inner edge of the base 35 is provided with recesses 38 and its ends are provided with rounded projections 38 forpurposes to be presently described. The aXle 31 is provided on its in- I ner vertical face with recesses 31 with which the recesses 38 register. The journals are further locked rigidly bymeans of the setscrews 39 threaded into the side bars of frame 4.

Turning upon the ournals- 30 are two mu- 7 tilated gears 40, 4O meshing with the, larger operating gears 13, 13 on rock shaft 10. Rigidly connected to the gears 13, 13 to rock therewith are the two stripper-operating hooks or cams 41, 41, and the two sheet-carrier lifting earns 42, 42; spaces being left between the stripper hooks 0r cams 41 and the gears 40, 40 for the lower ends of the punch actuating links 43, 43, which lower ends are pivoted eccentrically by pivots 43, see Fig. 8, to the gears 40, 40, while their upper ends are pivotally connected to the ends of the punch-carrying crosshead 50 which is guided on guide bars 51, the lower ends of which are mounted to rock on the aforesaid journals .30 between the cams 42, 42 and the sides of the frame 4. At the inner sides of the frame 4 next to the ends of square axle 31 and upon the journals 30 are mounted locking hooks 80, 80 to engage the rounded projecting encts 38 of the pin base35.

The crosshead 50, like those in my said patents, is provided with punches 52 registering with the anvil apertures, but these parts are now placed vertically and parallel to the filing pins so that the slotted sheet guides of said patents are dispensed with and the path traveled by the crosshead and punches from the punching position to that of transferring of the sheetsv from the punches to the filing pins is only very short, as will be readily seen.v This vertical arrangement greatly simplifies and improves my prior constructions. The stripper 53 extends across the lower face of the crosshead 50 and the punches pass through open slots 53 in it. p The stripper has depending arms 54 atits ends and these arms have guide lugs 55 on their inner sides sliding on the guide bars 51.

The outer sides of the arms '54 are provided at their lower ends with anti-friction 7 wheels 56 engaged by the two hooks or cams 41, 41 for first moving the cross head, punches and stripper over the filing pins and then towards the arms 54 by springs 57.

As the crosshead and stripper move clown- Wardly in the act of punching, the inner ends of the spring-pressed levers 57 lie under the lower ends of'arms 54 and so cause the stripper 53 to beheld positively against the lower face of the crosshead 50, but when the crosshead and stripper are moved over the filing pins by throwing lever 12 to the left as in dotted lines, Fig. 1, in doing which the initial movement of books 41 to the right will move the cross head and stripper over the filing pins and then the arms 55 will move from over the free ends of the levers 57 and so permit the hooks or cams 41, 41 to easilydepress the stripper and force the apertured leaves down upon the filing pins. Stops 8, 8 and 8, 8 limit the swin of the crosshead over the anvil.

In the return movement of the crosshead and stripper to the position over the anvil thearms 54 will be raised by springs 58 and again overlie the levers 57 and these springs 58 will also exert a rearward as well as an upward pull on the arms 55 and so draw the crosshead and stripper back over the anvil.

Springs 58 may be of any desired kind, but I have shown coiled springs coiled about pin 59 on the inner sides of the uprights 2, 2 with their free ends or arms extending under studs 61, projecting from the arms 55 just above the parts 56 engaged by hooks 41, 41. By means of the slots 53 in the stripper bar 53 the crosshead 50 and stripper 53 will be permitted to swing away from the upper ends of the filing pins after the leaves have been stripped from the punches and without the stripper havin to be raised above the upper ends of the filing pins. The time for Inovementis thus shortened.

As before stated, a gage plate 19 is provided for the end edges of the leaves to be punched and a gage carried by the crosshead 50 is provided for the side edges of the leaves. This side gage is formed of a spring 7 0 secured at one end to a pin 71 projecting from a slotted slide or plate 72 and having a depending arm- 73 to engage the sheets. The sprin passes under a pin 74 and over a pin 5 which prevent it from turning on pin 71 and yet allow it to flex upward should the lower end of arm 73 engage the top of a pile of sheets or top of anvil. The plate or slide 72 is secured in any desired position by means of a screw 76 passing through its slot into the crosshead.

- To operate the hooks 80 before referred to which engage the ends of the pin base 35 I provide a transverse rock shaft 81 mounted in hearings in the sides of the base and having a crank handle 82 at the same side as the operating lever 12. This rock shaft 81 is provided between its ends with an eccentric 83 encircled by an eccentric strap 84 to which is connected one end of a rod 85, the other end of which is connected to an arm 86 depending from the middle of a crossbar S7 rigidly connecting the two hooks 80 below their axes so that the turning of the rock shaft 81 will cause the forward or rearward throw of the locking hooks 80.

At the right of the punching mechanism is located the horizontally disposed sheetcarrier 90 for the pile of punched sheets.

This sheet-carrier 90 overlies at its inner end the base 35 which carries the sheet-receiving pins 36 and has slots 91 to straddle the pins 36. The outer end of the carrier 90 is pivotally mounted by means of pivots 92, 92 between the upper or outer ends of two short arms 93, 93 rigidly connected by a transverse bar 94, one of these arms 92 being extended upwardly to form an operating handle 95.

The lower or inner ends of these arms 93, 93 are connected to the upper ends of vertical slides 96 by means of pivots 97; these arms 93, 93 projecting above and below the bar 94 and in eifect forming T-ends therefor. The slides 96 are mounted in vertical guideways 98 on the inner sides of the base 1 and their downward movement is limited by means of depending brackets 99 having inturned flanges 100 at their lower ends, which flanges underlie the lowerends of the guide ways 98. The inner sides of these slides 96 are provided with actuating studs or lugs 101 adapted to be engaged by the operating arms 102 of vertically rocking and laterally sliding bell-crank levers 103 loosely mounted on the ends of rock shaft 81 and provided with inwardly projecting sleeves 104; having their innerends formed or provided with inclines or cams 105 acted upon by studs 106 projecting from rock shaft 81 to force the bell-crank levers 103 outwardly and under the studs 101 of slides 96 when the crank handle 82 is turned to the right, which movement of the crank handle also causes the locking hooks 80 to engage the ends 38 of base 35 carrying pins 36. p v

The bell-crank levers 103 are drawn inwardly and from under the studs 101 by means of a contractile spring 108 whenever the crank handle 82 is swung to the left to release the locking hooks 80.

The bell-crank levers 103 are actuated to raise and lower the right hand end of the sheet-carrier by means of operating rods 110 pivotally connected at their outer ends thereto and pivotally connected at their inner ends to ratchet segments 111 secured to or forming parts of the gears 40, 40. These ratchets 111 are engaged by the inner-ends (left) of pawls 112 pivoted between-their ends to the inner sides of base 1 and extending at their opposite ends under the rock shaft 81, which is there provided with projections or cams 113 adapted to depress the tails of the pawls against the action of springs 112 and release their inner ends from the ratchets 111 when the crank handle 82 is swung to the left-hand position. The sheet-carrier'90 is prevented from swinging too far down into the base by means of stop lugs 115 secured to the upper edges of the sides of the base. The sheet-carrier 90 is provided on its under side with a longitudinal shaft 119 having an operating handle 120 at its outer end projecting up through a transverse slot 121 in the end of the carrier 90. A spring-pressed latch 122 has a pro- .jection 123 which looks the handle 120 when swung towards the far side of the machine or away from the operator. The inner end of the shaft 119 has a head 124 lying between the inner ends of two slides 125 mounted in guides 126 just in rear of the slots 91 and pressed towards each other by a bow spring 127 as in said prior patents.

These slides 125 are now, however, provided with two locking pins 128 adapted to pass under the square axle 31; the recesses 31 and 38 heretofore described being provided in the axle 31 and base 35 respectively to permit the pins 128 to pass down below the axle and then be moved thereunder to lock the inner end of the carrier 90 down upon the base 35 during the sheet compressing operation. The outer endsof the slides 125 when the pins 128 are under the axle 31 projectoutwardly far enough to lieover the two .lifting cams 42, 42 so that as the cams areraised the inner end ofvthecarrier 90 will be correspondingly raised, at which time the lifting arms102 of the bell crank levers 103- will i be simultaneously :raised to lift theouter end of the carrier. The carrier will be lifted evenly at both ends and sowill always lie horizontally. The two slides 125 areprovided with friction grips or catches 130formed of bent springs; one endof each of. which is fixedly connected to its slide, while the outer orbiting end lies next to an aperture 131 inthe carrier 90 just as in my Patent 1,346,17 9. i

- The clamp. 135 has the depending legs 136 adapted to enter-the apertures 131 and to be engaged by the. grips or catches 130 as in mysaid patent, but it is held against the upward pressure of the rising. carrier 90 during the act of compressing a pile of sheets by means of oppositely sliding bolts 137 mounted on its top crossbar and pivotallyconnected at their-inner ends to a pivoted operating-handle 138.. By moving this handle in one direction the bolts may be projected, at their outer ends, through apertures 139 in the uprights 2, 2, and so look the clamp.

- The-operation is 'as follows The carrier 90 will be in its lowered position and its hand :lever 95 will be swung up, which movement will movethe carrier longitudinally and bring its slotted end over the base of-the receiving pins and the two locking pins 128 willat the same time pass under the fixed axle 31, thus'securely locking the car rier-down on the pin base; and .to the said axle. The crank handle 82 will also be swung over to the left, which will throw the bell-crank levers from under the studs 101 so that the outer end of. the carrier will be disconnected from its operating mechanism and will release the pawls 112 from the ratchets 111 to allow the lever 12 to be moved in either direction. The handle 120 will bedrawn towards the operator sothat.

the slides 125 will be out of the paths of their lifting cams and the hooks will bemoved from over the ends of the filing pin base. The lever 12 will now be moved to its middle position, which will bring the punches into vertical alignment with the anvil apertures. I

Sheets will nowbe placed with their ends to be punched "overlying the anvil and evened bythe'gages.

The lever 12 will nowbe moved to the right, which will cause the punch-operating links 43, 43 to pull the crosshead, its punches and the stripper downwardly until the punchespass through the sheets. I By now moving the lever to its middle position the cross head punches and stripper will be lifted; the punched sheets being lifted with to the. left the crosshead ,will be moved to the right until the punches register with the sheetreceiving pins 32 and then by continuing to move; lever 12 to the left. the stripper-operating hooks41, 41 will depress the stripper and cause it to,.transferthe punched sheets tothe pins 32; Duringthese operations the sheetcarrier. 90 will. not have been raised or lowered at all, as in my patented constructions before referred to. Assoon as a pile of sheets hasbeenformed ready for binding the clamp 135' will'be placed thereover with its legs extending down through apertures131 and its locking bolts 13? entered into apertures 1 39.

Handle 120 is-now moved away from the operator till locked by its spring catch and this will have moved the slides;125..outwardly andacross their lifting'cams. {The crank handle 82 is now turned to: the right, which, will move the bell-crank levers 103 outwardly and bring their lifting arms 102 under the studs or lugs 101 and. at thesame time throw the hooks80 over the base of the receiving pins to loclrthe base independently ofthe carrier 90 and will also release the pawls 112 and allow them to engage the ratchet segments 111. Lever12 will now be moved to the right, which will cause the car-. rier to be lifted bodily at both ends simul taneouslyand. .then-held up by the action of the ratchets-112. l i. M I i This upward movement of the carrier .90 will force the pile of. sheets upwardly against therclamp 135 and when the pile is sufficiently. compressed handle 120 will be given a further movement'away from the operator, which. will cause a further outward movement ofslides 125 and bring the friction. catches 130 into biting engagement. 3

with the legs ofthe elam'p'.- I

The pile of-punched heets will now be firmlyclamped to thecarrier 90. .If the pile of sheets is-to be'secured together by binding sleeves such as :shown at Yin; my Patent 1,346,179 such sleeveswill have been placedv on the receiving or filing pins and their upper ends will now be upset, or where the leaves are to .be .sewed the carrier'90 withthe pile of leaves will be swung up as in Fig. 10 of my Patent 1,255,112. This is accomplished by throwing. lever 95 to the right until the parts assume the position shown in Fig. 6. I

The carrier or table 90 may be moved from over the filing pin base by simply swinging the hand lever 95' to the right,which will pull the inner end o-ftcarrier or table v90 from over the unlocked baseofthe filing pins and so permitthe same to be lifted off of the fixed axle atany time. 5
